, A'roMIzER.

Be it known that I,.JOHN R. BALLENTINE, a citizen yof the'United States, residing at Toledo, inthe count of Lucas and State of Ohio, have invente certain-new and useful Improvements in Atomizers, of which the following is a specification. 'u

This invention'relates to atomizers of the vacuum type, wherein liquid in any bottle or vessel may be exhausted `therefrom and discharged through a spraying head or nozzle by means of a blast bf air In this type of atomizers it is necessary that there be two tubes, one for the air and the other for sprayed.

li uid, and it is also desirable that the two tu es be merged into one at some point of their lenvth, inl orderthat the air blast may be broug'lit into the`most efl'ective position with respectto the nozzle or outlet for the liquid, and also in order that the nozzle ma be protected and inclosed by a suitable hea It 1s old in this type of atomizers to connect the 'tubes by means of a block, containin air and'liquid passages, 4but this has the objection that it is expensive and is of such large size that it cannot conveniently enter the passages of the nose orthe throat. l I In the present invention theconnection between the pipes is formed by simply ofi"- setting one pipe and running the other one into it,l through a hole'in the side. This cheapens the cost of construction by avoiding the expense of a block at the joint and also reduces its size so thatthe head can be readily entered A further feature of the invention is the This makes the atomizer more compact, and -cheapens the construct1on and simple and eflicient manner in which .thef two pipes are supported by the cap, the tubes being set and ysupported crosswise in the cap.

ives added strength to the tubes, andavoi s any joint between thev tubes' within the cap.l

Figs?) is an elevation of a modification and g. 4 is a longitudinal sectional yiew of the spraying-head thereof. Referring specifically to the drawing, 5 denotes a) glass or other vessel which 'contains the, fluid to .be atomized.' The vessel'is closed by a cap 6 whichcarri's the' fluid Specification of Letters Patent.

tube 7 and the air tube 8, the formerl depending into the'bottle from the cap as in dicated at 9.. The air'tube extends transversely through the cap above the fluid tube and has at its inner end a nipple 10 for attachmentof the bulb or other suitable means for producing an air blast. The fluid and air tubes extend in parallelism rfrom the cap, and at any portion of its length the air tubeis bent laterally as at 11 and continued Ain an offset portion 12 at the extremity of which is the spraying-head 13. The bend 11 hasl a/n opening 14 through which the fluid tube enters the offset portion 12 of the air.

tube. The fluid tube extends lengthwise through the offsetportion 12 of the air tube and is arranged concentricallytherein, with t sufficient space between the tubes to permit the passage of the air to the spraying-head. The extremity of the fluid tube 7 iscontracted as at 15 to form a nozzle, and behind the contracted portion, the tube is threaded eX- ternally as at 16 for attachment of the spraying-head 13. Said head has a reduced rear extension 17 which enters the air tube and screws on the threaded portion 16 of the fluid tube. The extension 17 is formed with an enlargement or collar 18 whereby it is spaced from the inside of the air tube. The nozzle 15 extends into the bore 19 of the head and beyond the mouth of the nozzle said bore is contracted as at 20 through which contracted portion the fluid is discharged from the head 13. Behind the collar .18 the extension 17 has openings 21 which communicate' lwith the bore L19 behind the mouth of the nozzle 15.

In use, the air in the tube 8 flows through the openings 21,-past the nozzle 15 and out ofthe head 13 through the bore 20. This creates a suction at'the nozzle 15 and in-f duces a flow of liquid therefromA *whichv is blown through the bore 20 in the form of a and the air tube inside the same. v case the fluid tube is indicated at 22 and theair tube at 23. `The lateral bend which 'in this instance is in the vfluidv tube is indicated at 24 and the offset portion of said tube is indicated at 25. The'spraying-head e' extension 17 as before, which enters lthe fluid tube and screws on the air tube as indicated at 26. The extension 17 is spaced from the fluid tube by a collar 18 as before, and behind this collar v,are openings 27 which communicate with the bore 28 of the cap 13. The action is substantially the same as in the previous -ducing the size ofthe spraying'head to that of a single tube, the cost of olf-setting the tube and drilling the hole at the oi-set bev ing very much cheaper than to use a block which must be drilled and constructed to lit, The construction is also `quite strong and'rigid inasmuch as both tubes are fas-l tened together -and support -each. other.

i -Furthermore, the tubey for the liquid, at the free end thereof,l is or may be made freel from the air tube, and consequently may be bent at a right angle at any place or point along its length, to enter any bottleor vessel.
